The matrix is fixed to always have zeros down the left-hand side, apart from the first row, which ensures that only one of the minor matrices is non-zero. I think this is a really artificial example, and doesn't adequately assess whether the student can compute the determinant of a big matrix.

• The description should describe how the matrix is generated.
• I've tagged in the taxonomies.
